Compiled simulation is a well known technique for improving the performance of instruction set simulators at the cost of compilation time. However the compilation time overhead makes such usage of compiler optimizations impractical especially for large applications. In this paper, we propose a hybrid compiled simulation approach that is simple, generates an optimized decoder and has almost no c...

When parallel programs are executed on multiprocessors with private caches, a set of data may be repeatedly used and modiied by diierent threads. Such data sharing can often result in cache thrashing, which degrades memory performance. This paper presents and evaluates a loop restructuring method to reduce or even eliminate cache thrashing caused by true data sharing in nested parallel loops. T...

Smart play-out is a method for executing declarative scenariobased specifications, which utilizes powerful computation methods to compute safe supersteps, thus helping to avoid violations that may be caused by näıve execution. Major challenges for smart play-out are performance and scalability. In this work we show how to accelerate smart play-out by adapting and applying ideas inspired by form...

This paper presents a handover optimization scheme in LTE for a variety of velocities. This scheme adjusts the time-to-trigger parameter based on received signal strength. The proposed algorithm demonstrates a more enhanced performance during a data link failure and ping-pong effect than existing algorithms focusing on a user’s position.

variety of energy–ecology optimizing means that optimum result of fuel combustion is focused not only on the direct efficiency of its usage but also on minimum environmental damage. best possible fuel combustion connected with controlled level of chemical underburn is considered to be one of the simpliest, cheapest and the most effective methods of optimizing. it is essential to notice that the...

while conventional data envelopment analysis models set targets separately for each decision making unit, centralized recourse allocation model is presented where there is a centralized decision maker that supervises all the operating units. optimizing of total input consumption and total output production is the main aim of this model. in this paper, firstly the centralized output production m...

micrornas constitute a group of small non-coding rnas that negatively regulate gene expression. aside from their contribution to biological and pathological pathways, altered expression of micrornas is reported in bio-fluid samples, such as serum. to employ serum's micrornas as potential biomarkers, it is crucial to develop an efficient method for microrna quantification, avoiding pre-analytica...

Evolvable hardware distinguishes itself from conventional hardware by its ability to adapt to its environment, and change its structure to perform better on a given task. The principle of adaptation is based on evolution, and has great potential to be used widely in the future, in many areas. This paper discusses the progression in the field of evolvable hardware. It covers the current state of...

Performance measurement that accurately reflects the goals of fund investors and managers has long been a topic of active discussion. Most modern performance measures differ from classical ones (such as the Sharpe ratio) in two key ways; first, they reflect the market practice of assessing performance against a benchmark, second, they account for the asymmetry in returns distributions by separa...
